SANITARY EGG BEATER.

Application filed August 9, 1926.

This invention aims to provide novel means whereby beaters may bedetached from the frame of an egg beater, to permit cleanmg. i

l' ith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the drawings Figure 1 shows in elevation, an egg beater wherein theinvention has been embodied;

Figure 2 is a section on the line 22 of Figure 1;

Figure 3 is a section on the line 3-3 of Figure 1;

Figure 4 is a bottom plan of the anchor;

Figure 5 is a fragmental plan showing the anchor and a portion of theframe.

The numeral 1 designates a frame of an egg beater, the frame including across piece 2 and a loop-shaped foot 3. Loop-shaped beaters 4 are shownand are equipped at their ends with tubular bearings 5 which holdpinions 6 on the upper ends of the beaters 4.

The pinions 6 mesh with a gear wheel 7 on a shaft 8 journaled in theframe 1, the shaft being operated by means of a crank 9, a means thusbeing provided whereby the beaters may be rotated. The tubular bearings5 are journaled 011 pins 10 extended downwardly from the cross piece 2.Tubular bearings 11 are mounted in the lower portions of the heaters 4.The details above enumerated form a part of a known egg beaterconstruction, and no novelty is claimed for them, saving in so far asthey may enter into combination with parts hereinafter described.

In carrying out the invention, a U-shaped latch 12 is secured to 14, bya drop of solder, or otherwise, to the upper surface of the bottomportion of the foot 3. The latch 12 has movable resilient arms 15. Ananchor plate 16 is provided and carries upstanding journal pins 17.Intermediate its ends, the anchor plate 16 is supplied with a keeper 18in the form of a stud, having a pointed up- Serial No. 128,250.

per end and reduced intermediate its ends, to form a circumscribinggroove, as clearly shown in Figure 3. The anchor plate 16 is equippedintermediate its ends with lateral ly extended arms 20 having upstandingfingers 21. The bottom part of the foot 3 has an opening 19. There areseats or openings 22 in the bottom part of the foot 3, the seats 22being located on opposite sides of the opening 19.

The stud 18 extends upwardly through the opening 19 in the foot 3, andthe reduced neck of the stud 18 is received between the springs arms 15of the latch 12. Thus, the anchor 16 is held securely in place, in theposition shown in Figure 3. The journal pins 17 on the anchor arereceived in the bearings 11 at the lower ends of the heaters, and, thus,the heaters are held at their lower ends for rotation. The fingers 21,being received in the seats 22, prevent the anchor 16 from swinging withthe stud 18 as a center.

\Vhen the operator wishes to take off the heaters 4, he simply pullsdown the ancnor plate 16, detaching the stud 18 from the arms 15 of thelatch 12 and withdrawing the journal pins 17 from the bearings 11 in thebeaters 4. Then, the heaters 4 may be slid downwardly off the topjournal pins 10, and the heaters are entirely free of the frame, itbeing possible, then, to wash and sterilize all parts of the machine.This is a distinct advantage, since it is well known that an egg beater,including the loop-shaped beaters 4, is hard to keep clean, in presentconstructions, wherein the heaters are permanently assembled With thesupporting frame.

hat is claimed is 1. A device of the class described comprising a frame,a heater detachably journalecl on the frame, an anchor whereon theheater is journaled, a keeper on the anchor, and a latch carried by theframe and co operating with the keeper to hold the anchor on the frame.

2. A device of the class described comprising a frame, a beaterdetachably journa-led on the frame, an anchor whereon the beater isjournaled, a stud carried by the anchor, a latch on the frame andengaging the stud, and interengaging elements on the anchor and on theframe which cooperate to prevent the anchor from swinging on thetachable connection between the anchor and stud. the frame.
